After he avoided the plants, Batman quickly assembled the Ultra Batclaw and escaped to take down Poison Ivy. He then used it in order to get access to the control rooms in the Caves that pumped the water into the Gotham City River. Afterwards, Batman used the Ultra Batclaw for the rest of the incident.

Arkham City Incident

The Ultra Batclaw could not be acquired in Batman: Arkham City, but rather, the normal Batclaw was used.

Arkham Knight Incident

The Ultra Batclaw was again left out, for unknown reasons.

Trivia

It was unknown why the Ultra Batlclaw wasn't able to be acquired in Arkham City, although it was possible that it was still a prototype during Arkham Asylum, and that it was still in testing during the events of Arkham City. Alternatively, it could be possible that Batman invented the gadget on the spot given how out of control Poison Ivy and her plants were getting, and he created it from spare Batclaw's to combat and traverse the changed landscape of Arkham Asylum.
